Detailed Description
The following detailed description of the present application is provided in further detail with reference to the accompanying drawings.
The application aims at providing a sterilization control method for washings, which reduces the sterilization water consumption and the power consumption required by heating, thereby realizing the effects of short sterilization time and low energy consumption, as shown in fig. 1, and comprises the following steps:
step S11: it is detected whether a laundry sterilization program start signal is received.
The laundry sterilization program start signal is issued by the user using a control interface, a key, a control terminal, etc., and is not limited in this application. After the user initiates the laundry sterilization program start signal,
step S12: the low flow inlet valve is opened to allow water to flow through the heating module and the spraying device in sequence to achieve atomization.
The spraying device is arranged in the washing cavity, after the sterilization program of the washings is started, the low-flow water inlet valve on the water inlet pipeline is controlled to be opened firstly, then the heating module is started, the low-flow water flows through the heating module through the water inlet pipeline to be heated and warmed up instantaneously, the warmed up hot water is sprayed into the washing cavity by the spraying device, such as the inner barrel of the drum washing machine or the inner barrel of the pulsator washing machine, and then the heated hot water is sprayed onto washings in the washing cavity.
Step S13: the motor is controlled to drive the washing cavity or the pulsator in the washing cavity to stir so as to realize the overturning of the washings.
The inner cylinder of the drum washing machine is controlled to rotate to drive the washings to turn over, or the impeller in the inner cylinder of the impeller washing machine is controlled to rotate to drive the washings to turn over, so that the sprayed hot water is uniformly sprayed on the washings, the washings are heated up rapidly, and the effects of mite removal and sterilization are achieved.
For example, as an embodiment, the low flow water inlet is controlled to be about 0.3L/min, the heating module adopts a 1400W instantaneous heating module, so that the normal temperature water at 25 ℃ can be quickly heated to high temperature at 70 ℃, the proper survival temperature of mites, bacteria and the like is between 20 ℃ and 30 ℃, when the environment temperature is raised to between 40 ℃ and 50 ℃, the survival time curve of the mites and bacteria is suddenly turned down, and when the temperature is higher than 50 ℃, the survival time of the mites is very short, so that the mites and the bacteria can be effectively removed by using the washing sterilization control method provided by the application.
In the embodiment of the application, the rotation of the washing cavity or the pulsator in the washing cavity is controlled in the following manner: the motor is controlled to alternately operate in a continuous operation mode and an interval operation mode to form an operation period, and the operation period is set in a circulating mode. Here, the continuous operation mode is to control the motor to continuously operate for a first set time, and the interval operation mode is to control the motor to repeatedly operate in a mode of stopping for a third set time after operating for a second set time; wherein the operation time of the continuous operation mode is controlled to be longer than that of the interval operation mode.
For example, after the low-flow water inlet valve is opened for 5 seconds, the heating module is started, the low-flow water inlet is quickly heated to more than 70 ℃ through the heating module, and the low-flow water inlet is sprayed on the washings by the spraying device and keeps spraying; during the spraying period, the motor is controlled to work to drive the washing cavity or the pulsator to rotate for 40 seconds to turn over the washings, then the motor is controlled to work for 1 second and stop for 4 seconds until the period of 20 seconds is satisfied, so that the washings are turned over for 60 seconds in one cycle, and 15 cycles are circulated for 15 minutes.
Step S14: and when the set time is up, the low-flow water inlet valve is controlled to be closed so as to finish the sterilizing process of the washings.
According to the steps S12 and S13, the sterilization is performed until the set time is satisfied, where the set time is a sterilization time period capable of achieving the maximum sterilization efficiency under the condition of injecting hot water temperature, or, taking the above embodiment as an example, the sterilization rate of 99% can be achieved by setting the set time to be not shorter than 10 minutes under the condition of injecting hot water to 70 ℃.
And controlling to close the low-flow water inlet valve and simultaneously closing the heating module, and naturally cooling the heating module.
Above-mentioned, because the heating module only needs the water of heating low flow to need not to heat a large amount of water, has reduced the length of disinfecting on the one hand, has also reduced the power consumption on the one hand, has solved the long and power consumption's of current washings sterilization technical problem.
In the embodiment of the application, the timing control execution of the sterilization program of the laundry is matched with the execution of the sterilization program of the laundry before the start of the washing program, and the sterilization is performed in advance before the washing, so that the power consumption can be reduced to the greatest extent, and in particular, before the implementation of the step S12, whether the washing program is started or runs completely is judged; if yes, controlling not to open the low-flow water inlet valve; that is, the laundry sterilization program controls the wet laundry to be washed to prevent the temperature of the sprayed hot water from being lowered before the start of washing, thereby reducing sterilization efficiency.
